Income tax in India is governed by Entry 82 of the Union List of the Seventh Schedule to the Constitution of India, empowering the central government to tax non-agricultural income; agricultural income is defined in Section 10(1) of the Income-tax Act, 1961. Income-tax law consists of the 1961 act, Income Tax Rules 1962, Notifications and Circulars issued by the Central Board of Direct Taxes (CBDT), annual Finance Acts, and judicial pronouncements by the Supreme and high courts. The government taxes certain income of individuals, Hindu Undivided Families (HUF's), companies, firms, LLPs, associations, bodies, local authorities and any other juridical person. Personal tax depends on residential status. The CBDT administers the Income Tax Department, which is part of the Ministry of Finance's Department of Revenue. Income tax is a key source of government funding. The Income Tax Department is the central government's largest revenue generator; total tax revenue increased from in 1997–98 to in 2007–08. In 2018–19, direct tax collections reported by the CBDT were about 11.17 lakh crore (). History Ancient times Taxation has been a function of sovereign states since ancient times.

In the Manusmriti, Manu says that the king has the sovereign power to levy and collect tax according to Shastra: The Baudhayana sutras note that the king received one-sixth of the income from his subjects, in return for protection. According to Kautilya's Arthashastra (a treatise on economics, the art of governance and foreign policy), artha is not only wealth; a government's power depended on the strength of its treasury: "From the treasury comes the power of the government, and the earth, whose ornament is the treasury, is acquired by means of the treasury and army." Kalidasa's Raghuvamsha, eulogizing King Dilipa, says: "it was only for the good of his subjects that he collected taxes from them just as the sun draws moisture from the earth to give it back a thousand time." 19th and early 20th centuries British rule in India became established during the 19th century. After the Mutiny of 1857, the British government faced an acute financial crisis. To fill the treasury, the first Income-tax Act was introduced in February 1860 by Sir James Wilson (British India's
